Senator Hanson has appealed the suspension, describing it as part of the ongoing efforts of the left to stop freedom of speech and silence anyone with whom they don't agree.

"I don't see how my tweet was somehow offensive and potentially harmful, if those tweets wishing I'd fall of Uluru are not," Senator Hanson said.

"This is just a concerted effort by the left to once again push for the censorship of conservative politicians and commentators, but I won't be silenced and I will keep working for the good of all Australians."
